Cryoablation is an FDA-approved, well established and relatively safe and painless technique for killing tumor using ultra cold. The procedure is conducted under CT scan imaging of the tumor.  The procedure is minimally invasive and involves placing an ultra thin needle through the skin (percutaneous) into a selected tumor mass.    Under conscious sedation, compressed argon gas is passed through the needle and into the tumor creating a lethal ice ball.  The ice ball is readily visible to your doctor under the CT scan so it can be controlled to only kill tumor tissue and avoid any normal tissues and vital structures.  The procedure is performed in an out-patient CT scan facility by a licensed physician specializing in interventional radiology.

Percutaneous cryoablation is now being used effectively by doctors to treat prostate cancer, certain kidney tumors and metastatic liver tumors. There are also physicians using cryoablation experimentally to treat primary liver cancer as well as certain lung and bone tumors and tumors within lymph nodes or on or near the skin surface.
